Transponder Chips

Transponder chips are likely to be found in cars that were manufactured within the last 20 years. It's the tiny piece of plastic in the head of the car key that has an RFID (Radio Frequency ID) chip with a code unique to your car.

The chip emits an low-level radio signal once it is activated by an electromagnetic field. This signal is then taken up by the antenna that is fitted around the barrel that controls your ignition in your car. This allows the computer in your vehicle system to determine if the transponder chip that is in the key is the correct one for your specific vehicle.

This is what stops doing hot-wiring or altering the vehicle's ignition system to start it. The chip inside the key also proves that you are the genuine owner of the vehicle. This will help reduce car theft.

When the transponder key is inserted in the ignition barrel, a circuit within of the induction coil will send out an electrical signal. The signal is received by the chip which sends a signal to the vehicle. If the computer in the car detects the signal as correct it will turn off the car immobilizer, allowing the engine to start.

If the vehicle does not recognize the transponder signal as being the right one, it will keep the engine from running and will notify you by flashing its lights and sounding a siren. automotive key programming near me is intended to discourage people from trying to hack into the vehicle, but it isn't a foolproof security measure.

When you press the button on a key fob the microchip sends signals to the receiver inside the vehicle with which it is paired. The receiver compares this information with the 'allowed' signals stored on the fob and either opens or closes the door. If the data doesn't match the signals, a chirping sound can be heard and the car isn't permitted to function.

Once the car has been associated with a particular fob, it can only receive signals from that device. Other fobs will not work with the car, even if they look identical. This safeguards the integrity of the computer system that runs the car and prevents unauthorized key fobs gaining control of it.

Most dealerships with newer cars will only accept cars with original fobs, or genuine replacements offered by the manufacturer.
